Processing Apparatus and Processing Method
First Claim
1. A processing apparatus for performing a predetermined process using a process gas at a prescribed flow rate to an object, the processing apparatus comprising;
- a process container comprising a placing table for placing the object;
an exhaust system having a vacuum pump and a pressure control valve for exhausting an atmosphere in the process container;
a gas injection unit having a gas ejection hole for ejecting the process gas into the process container;
a gas supplying unit for supplying the process gas to the gas injection unit while controlling the prescribed flow rate; and
a control unit for controlling the entire processing apparatus;
wherein the control unit controls the exhaust system and the gas supplying unit;
the process gas at a flow rate greater than the prescribed flow rate of the predetermined process is supplied for a predetermined short time while exhausting the atmosphere in the process container by the exhaust system; and
thereafter the process gas at the prescribed flow rate is supplied.

Abstract
A processing apparatus includes a process container having a placing table for placing a processing object, an exhaust system having vacuum pumps and a pressure control valve for exhausting atmosphere in the process container. A gas injection unit having a gas ejection hole is provided in the process container, as well as a gas supplying unit for supplying a process gas to the gas injection unit. The entire process apparatus is controlled by a controlling unit. The control unit controls the exhaust system and the gas supplying unit. When starting a predetermined process, the process gas at a flow rate greater than a prescribed flow rate is supplied for a short time while exhausting the atmosphere in the process container by the exhaust system, and then the process gas at a prescribed flow rate is supplied.

12. A processing method for applying a predetermined process to an object by supplying a process gas at a prescribed flow rate in a process container that includes an exhaust system, the processing method comprising the steps of;
-
supplying a process gas at a flow rate greater than the prescribed flow rate of a predetermined process for a predetermined short time from a gas channel while exhausting an atmosphere in the process container through the exhaust system; and supplying the process gas at the prescribed flow rate from the gas channel after supplying the process gas at the flow rate greater than the prescribed flow rate for the predetermined short time. - View Dependent Claims (13)
